The firmware addresses minor bugs including lesser RAM availability for end user and some overheating issues with the device.

XXUAMDC official firmware and the instructions provided in this guide are meant for the Galaxy S4 I9505 model only. It will not work on any other device. Verify the device's model number by navigating to Settings > About Phone.

Back up important data and settingson the phone (including contacts, SMS, MMS, images, videos, APNs and other internet settings)

Enable USB Debugging mode on the phone by navigating to Settings > Developer Options (if the device is running Android 4.0 or later) or go to Settings > Applications > Development (if the phone is running Android 2.3 or earlier). If the device is running Android 4.2, then do the following steps:

Go to Settings > About Phone

Scroll down to the bottom and choose Build Number

Tap the Build Number seven times to unlock or reveal the hidden Developer Options under Settings. Now, select the checkbox to enable USB Debugging mode from Settings > Developer Options.

Installation of the firmware requires ODIN flash tool in Windows OS. However, Linux (such as Ubuntu) and Mac OS users should use CrossOver Utility to run ODIN on the system.

As this is an official release, the installation of the firmware will neither increase the binary flash counter nor void the device warranty.

Windows 7 users should run ODIN as Administrator to facilitate full write access and prevent conflicts during the firmware installation process.

If "MD5 hash value is invalid" error message appears in ODIN message box, then just re-download the firmware to resolve the issue.

The instructions given in this guide are meant for reference purpose only. IBTimes UK will not be held liable if the device is damaged during or after the firmware installation. Users are advised to proceed at their own risk.

6. Connect the phone to computer with USB cable. At this point, the ID: COM port with a number turns Yellow or Green indicating the drivers are installed correctly or the device is connected successfully.

7. Choose the following files in Odin from extracted I9500XXUAMDE firmware folder using the respective checkboxes:

Choose the PDA checkbox, and click the file with '.tar' or '.md5' in its name.

Click the Phone checkbox, and choose the file named 'Modem' (ignore if there is no such file)

Select the CSC checkbox, and choose the file named 'CSC' (ignore if such file is absent)

Choose the PIT checkbox, and select the .pit file. Perform this step only if you got the .pit file while extracting in step 1 above, otherwise ignore it.

8. In Odin, enable Auto Reboot and F. Reset Time by selecting the checkboxes. But, the Re-Partition checkbox should be selected, only if a .pit file was used in the previous step.
